FRAMELESS EYEGLASS AND SPECTACLE MOUNTING.

Specification of Letters Patent.

Patented Oct. 20, 1914.

Application filed March 2, 1911. Serial No. 611,945.

To all whom it may concern:

Be it known that 1, JAMES HoYT BROWN, a citizen of the United. States,residing at Denver, in the county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Frameless Eyeglass andSpectacle Mountings; and I do-declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates generally to frameless eye glass and spectaclemountings, and particularly to means for preventing the lenses fromworking loose when attached to said mountings.

lhe invention has for its object to provide a simple, durable andinexpensive device or means that will permit lenses to be easily andquickly attached and rigidly adjusted to the said mountings, and itconsists of the parts and combination of parts hereinafter described andclaimed.

In the accompanying drawings forming a part of these specifications,Figure 1 is a side view of a frameless eye glass stud with a lensattached and showing my invention in combination with said stud andlens. Fig. 2 is a vertical. edge view of a frameless eye glass stud witha lens attached and showing part of my invention. Fig. 3 represents aheadless reversible screw. Fig. l represents a lens. Fig. 5 represents apair of trameless spectacles without temples, with my invention applied.

. Similar letters refer throughout all the views.

In the drawings, 1%. represents an eye glass stud with lens H attached.

B B are the lens straps which hold the screws E E, which are intended tobear against the edge of the lens, as shown in Fig. 1.

C C v are the ears of the said stud, and between said ears, the lens His held, as shown in Fig. 2.

' D represents a threaded hole through each strap B B, as shown in onestrap in Fig. 2.

E represents a headless reversible screw with a slot 1 at eachof itsends to permit the use of a screw driver.

F represents the holes through the ears (C C G H represents a lens.

" J represents a hole through the lens.

to similar parts G? represents a lens screw which passes through one earC, and the hole J in the lens H, and is thenturned or screwed into theopposite ear G which is threaded to receive the said screw.

K represents the head of the stud A which holds the eye glass spring andnose guard (not illustrated nor shown in Figs. 1 and 2).

When attaching lens H to the stud A, the screws E E in the straps B Bare flush with the underside of said straps.

The lens H is then put into position with ease. The lens screw G is theninserted through the hole F in the ear C and hole J in the lens H, andturned securely to place in the opposite ear C. The screws E E in thestraps B B are then turned gently to a point of contact against the edgeof the lens H, which forces the said lens away, so that the outer wallof the hole J in. the lens H is firmly in contact with the screw G, thuscausing a continuous pressure against said screw, the lens and screws Gand E E are then ridged and cannot work loose. The" straps B B are madesufficiently heavy so they cannot be bent by any strain on the lens. Thestraps on. mountings now in use are thin and made of soft metal, and areconstantly giving trouble by being bent away from the lens and allowingboth the lens and screws to become loose.

Referring to Fig. 1, it will be seen that the straps B B indicate asubstantial thickness so they cannot be bent by any pressure from thelens H, and it is not necessary for the straps B B to be as long as theordinary straps now in use on frameless mountings.

The screws E E may be set at any desired place on the straps B B. Saidmountings may be made so as to hold the lens tight by using my device inonly one strap.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent is:

1. A clip fastener for eye glasses having apertured ears, a screwcarried thereby and engaging a lens, lens straps upon the shank portionof said fastener, and a set screw carried by one of said straps andadapted to bear against the edge of the lens, as set forth.

2. An eye glass mounting having a lens strap provided with an adjustablescrew adapted to bear against the edge of the lens.

3. An eye glass mounting having oppositely extending lens straps, eachprovided with an adjustable screw adapted to bear against the edge ofthe lens. 4. An eyeglass mounting having a lens strap provided with areversible adjustable screw adapted to bear against the edge of thelens.

5. An eye glass mounting including a lens strap, ears projecting fromthe frame, a lens mounted between said ears, a member extending throughsaid ears and said lens, and a screw adjustably extending through saidstrap and bearing against the edge of the lens to hold the same rigid.

6. An eyeglass mounting having a lens strap provided with an adjustablemember adapted to bear against the edge of the lens.
